This Cusco 1-way limited-slip diff replaces the factory rear differential.

In the RS Model, the activation pressure is applied to the same direction of the initial torque with the utilization of a coil spring. Therefore, the initial torque is set lower than the MZ model enables a smoother and quicker initial clutch plates engagement from a non operational to a fully functioning state even despite a low initial torque rating is set. The virtues of a low initial torque setting is that it enables a smooth turn even while the LSD mechanism is not activated. Because of the coil spring design, it provides overall gentle and stable operation.

• 1-Way (45/0 (default) & 1.5-Way 55/20 deg), D-Size
• Initial Torque: 2-4 kg
